TRANSOM-LIFTER.

SPECIFICATION forming part of Letters Patent No. 417,182, dated December 10, 188 9.

Application filed 0mm- 23, 1889. Serial No. 327,887. (No model.)

To all whom it may concern:

Be it known that I, EMANUEL IIIPFARD, a citizen of the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented certain new and useful Improvements in Sash-Operatorsfor Greenhouses; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in means for opening and shutting the sash of greenhouses and other like structures, which improvements will be fully understood from the following description, when taken in connection with the accompanying drawings, in which- Figure 1 is a perspective view in detail of a sash-operator, showing the sash closed. Fig. 2 is a perspective showing a modification of the device, and Fig. 3 is a horizontal section of the gear and worm.

Referring by letter to the accompanying drawings, A designates a standard composed of two sections 1 and 2 of tubing or pipe, which rises perpendicularly from the floor of the greenhouse to the glazed roof thereof, and is rigidly secured to the under side of said roof in the desired position by means of a short T-arm at, the stem of which is pivoted in the bifurcated head 3, bolted to the-upper end of the casting or bracket B, secured to the upper end of the upper section 2 of the tubing. Below'the extension 4, on the upper end of the bracket B, is a box or hearing 5 for the horizontal line-shaft F, which is also journaled in suitable hangers depending from the sections of tubing together. The shaft 1) is provided with a hand-wheel D, provided with a handle by which to turn it.

M designates an arm, which is secured rigidly to the free end of a sash L and provided at its inner end with an upturned curve, to which latter is attached one end of a cord or wire p, the other end of which latter is attached to the line-shaft F and wound thereupon in the direction shown in Fig, 2. ,'l o the lower horizontal rail of the sash and in close relation to the arm M,I attach one end of another eord or wire 1), the other end of which is attached to and wound upon the line-shaft F ina direction opposed to the winding of the cord or wire 19 on the shaft and on the opposite side of a dividingcollar N, secured to this shaft by a set-screw a.

In lieu of the cords or wires above described, I represent in Fig. 1, which I deem it fair modification of the said parts, an arm M, which is rigidly secured to the line-shaft F and pivoted at its inner curved end to the inner end of the arm M. In this modification there is a positive connection between the motive power and the sash, while in the first instance, above described, the connections are flexible.

. It will be observed from the foregoing that I transmit by direct positive movements rotation to the line-shaft through the medium of a vertical shaft, on the lower end of which is the self-locking worm-screw, and on the upper endof which is the bevel-pinion meshing with a bevel gear-wheel on the line-shaft; also that, in case of Fig. 1,I flexibly connect the window-sash to the line-shaft, so that there is no liabililyof injurious shock or coneussion in the act of opening and closing the sash.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, in a sash-operator for greenhouses, of the sectional standard pro- 9 vided with a bracket having a pivoted adjustable T-arm at its upper end, the horizontal screw provided with a hand-wheel journaled in a bracket connecting the sections of the standard, a vertical shaft within the up- IOO per section of the standard provided at its upper end with a pinion and at its lower end with a worm-wheel engaging a screw, a lineshaft provided with a gear-wheel engaging the upper pinion, and means, substantially as described, for connecting the line-shaft with the Window-sash,substantially as specified.

2. The combination of the sectional standard provided with brackets, as described, the worm-screw horizontally arranged and provided with a hand-Wheel, the vertical shaft geared to the line-shaft, the arm M, rigidly i secured to this shaft, and the arm M, rigidly secured to the free end of the sash and pivoted l to the arm M, all substantially as described. In testimony whereof I affix my signature in presence of two witnesses. l EMANUEL I'IIPPARD.
